I like the CRC HD Corrosion Inhibitor a bit better than Corrosion X because it puts a heavier wax like coating on, I generally don't fully reapply it unless I find a lot of water in the servo or start to notice a twitch in the servo. I do give a little shot inside the servo after opening for inspection. I spray a quick shot just before putting the bottom on and set the servo bottom side down, so the CRC runs down and seals the seam and screw heads from inside.
